Thanks Bernadette, your words make so much sense and means even more. It also helps reinforce the fact that I'm doing the right thing. As a friend of mine always says about his dysfunctional family, "You can't pick your family".
I think Mom is finally starting to get it, but we'll see. One question I kept asking her, after sister was in temporary shelter, are you ready to let her live on streets now? Of course, she couldn't picture that, so I knew she wasn't commited to tough love, more or less her version of tough love with exceptions???
I will heed your comment about bowing out, detachment has to come into play and I'm trying my damndest. I guess it comes down to I may have to one day sever ties with my Mom if she doesnt' change too. My trust in my sister is shot, I've been dealing with this for 10 years now. It will take a long time before I can believe in her again and I know treatment isn't always the cure all. I pray she does, but we'll see...
